Title: Photo detector
Inventor: TAGUCHI KENSHIN
IPC: H01L31/10
Filed: 1978-02-10
Abstract: PURPOSE:To obtain a high speed, high sensitivity photo detector, by removing the region having a junction plane in an element structure possessing a planar junction structure, and covering with an insulation film layer so as to prevent the light in the intended wavelength range from entering the element by absorbing such light. CONSTITUTION:On a P<+> type Si substrate 1, a pi type Si layer 2 identical with the substrate is formed by epitaxial growth,  and phosphorus is selectively diffused thermally by using a thermally oxidized SiO2 film, and N+ type Si layer 3 and phosphorus are similarly ion-injected to form an n-type Si layer 4 by thermal diffusion. Using a silane compound  having such thickness that does not reflect to the wavelength of the incident light, a layer is formed with Si3N4 film 7 by CVD. In order to prevent the light from entering from the outisde of the upper part of the junction plane, polycrystalline GaAs is grown to form a layer 9, so that a majority of light having an energy larger than the forbidden band width of GaAs may be absorbed, thereby never reaching the Si layer. Thus, a high speed, high sensitivity detector may be obtained.

Filed: 1986-01-25
Abstract: PURPOSE:To contrive to enhance detection accuracy, by performing the adjustment of the sensitivity of a gas sensor under a purified air atmosphere after the assembling of said gas sensor. CONSTITUTION:The adjustment of the sensitivity of a gas sensor of which the sensitivity is adjusted after assembling is performed under a purified air atmosphere. Because of this, air is at first compressed by a compressor while the compressed air is passed through a catalyst to oxidize, adsorb and remove noxious gas in air and the air from which the noxious gas was removed is passed through a filter to remove fine particles remaining in the air. The adjustment of sensitivity is performed by humidifying purified air by bubbling the same through purified air or may be performed by humidifying purified air by a humidifier.

Abstract: PURPOSE: To enhance the efficiency of recovering iron and Cr by dissolving mixed sludge of hydroxides of a plurality of valuable metals and iron hydroxide in an acid; adjusting the soln. to a specified pH range; and dissolving coprecipitated valuable metals other than iron and Cr hydroxides in an acid.  
     CONSTITUTION: An acid such as sulfuric acid is added to mixed sludge of hydroxides of valuable metals such as Cr, Cu, Zn and Ni and iron hydroxide to dissolve all of the metals, e.g. at pH=1. At this time, it is required that an oxidizing agent such as NaClO is added during the dissolution to convert divalent iron into trivalent iron. An alkali such as NH 3  is added to the soln. to adjust the soln. to a pH value above a Cr hydroxide forming pH range and in a divalent metal hydroxide forming min. pH range, e.g. pH 5.2, thereby precipitating iron and Cr as hydroxides. An acid such as dil. sulfuric acid is then added to the precipitates to adjust the soln., e.g. to pH 3.7 and dissolve other valuable metals coprecipitated with iron and Cr. Thus, iron, Cr and other valuable metals are efficiently separated and recovered.

Abstract: PURPOSE:To discriminate rapidly and simply the appropriateness of the etching ability of a  fatigued etching liquid by a method wherein a penetration characteristic region wherein an  etching liquid having the fixed specific gravity can attain a prescribed quantity of etching is  set as an allowable fatigue region, and the fatigued etching liquid is diluted to be of prescribed specific gravity so as to measure the penetration characteristic thereof. CONSTITUTION:A liquid SL to be inspected is prepared by diluting a fatigued etching liquid  used repeatedly for manufacturing a photogravure to be of prescribed specific gravity, and it  is put, as a liquid drop, on the surface of a resist 14 which is closely fitted on the copper layer 36 of a photogravure material for testing. Then an electrode 16 connected with a power source  +VCC and an electrode 18 grounded via a resistor R2 are made to contact with the liquid drop SL, and the fall of the resistance R3 of the resist 14 due to the penetration of the liquid  after the drop SL is put on is estimated by measuring a time required for the change VB in potential of the electrode 18 falling down below a threshold voltage VTH, and is displayed 30  as the penetration characteristic of the liquid. Then, it is checked whether or not the displayed value is within an allowable region which is set beforehand on the basis of the difference in  time required for penetration between a new etching liquid and the etching liquid losing almost all of the etching ability and being diluted to be of prescribed specific gravity, and thus the  appropriateness for use of the fatigued liquid in terms of etching ability can be discriminated  rapidly.
